Detailsinfo

A vulnerability, which was classified as critical, has been found in Anthropic claude-code up to 1.0.104. Affected by this issue is an unknown code. The manipulation with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Claude Code is an agentic coding tool. At startup, Claude Code executed a command templated in with `git config user.email`. Prior to version 1.0.105, a maliciously configured user email in git could be used to trigger arbitrary code execution before a user accepted the workspace trust dialog. Users on standard Claude Code auto-update will have received this fix automatically. Users performing manual updates are advised to update to version 1.0.105 or the latest version.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2025-59041 since 09/08/2025. The exploitation is known to be easy. The attack may be launched remotely.
